A Virtual Liver, a Better Chance of Life

The reconstructions can be transmitted to external experts in any location, for consultation in real time just before surgery, the inventors say. Collaborative decisions can be made and optimal therapy planned with the best possible diagnostic support, before real surgery is attempted. Simulation of laparoscopic and robotic surgery, with tissue resistance, can be used either to practice the exact surgery proposed for an individual patient, or also for training several surgeons simultaneously.

Medical imaging of organs and tissues has contributed greatly to diagnosis and therapy planning, especially in the treatment of cancers, which are the major cause of deaths worldwide. However, the 2D scanning images possible until now have been difficult to interpret and it has not been possible to consult others who are not present in person. Now, software for 3D-imaging of the blood vessels of a patient's liver has been developed.

Until now, liver surgery has been based on the anatomy classically described by Couinaud in 1957. But the 3D modelling has shown that up to 50 percent of patients have a significantly different liver structure from the Couinaud description. "Thanks to the 3D modelling," says Professor Luc Soler of the Institut de Recherche pour les Cancers de l'Appareil Digestif (IRCAD), "the future of liver surgery has gained more precision through accurate definition of the liver's blood vessels."
